"ALFRED B. FOWLER. OF BOSTON, MASSACHUSETTS, ASSIGNOR T0 UNITED SHOE IivIA- CHINERY COMPANY, OF PATERSON, NE? J ERSEY, A CORPORATION 0? NE! JERSEY.

-Ib all whom it may concern: Y Be it known that- I, ALFRED B. FOWLER, a citizen of the United States, residing at Boston, in the county of Suffolk and State'of Massachusetts, have invented certain new and useful Improvements in Bolling-Ma'- chines; and I do hereby declare the following to be a full, clear, and exact description of illQ'lIlYGHilOIl, such as Will enable others skilled in the art to which it appertains to f make and use the same.

The res nt invention relates. to builin r machines and more particularly to that class render the machine capable of producing a better surface, increase the amount of work i which can he done by the machine, prolong the life of the abrasive covering. and reduce. the number and extent of the movements which must be imparted to the boot or shoe by the operator during the butting operation. Such. machines have. however, been so constructed that onl a slow reciprtx'ating'movemeat as compared to the s weed of rotation can he imparted to the but 'ng roll so that the objects sought have not been attained, the reciprocating movement of the butting roll being so slow as compared with its speed of rotation as to have little or no etl'ect upon the action of the roll or-on the character of the surface produced. The comparatively slow reciprocating movement imparted to the butlin g roll has been neeessi tated by-the fact that the mechanism for reciprocating theroll has been arranged to reciprocate the shaft upon which the roll is mounted and also by the fact that when two butting rolls have been provided as is usual in this class of machines, the mechanism for reciprocating the rolls has been arran ed to reciprocate both rolls simultaneously. in the same direction.

BUFFING-MACHINE.

chine is rotated at a speed of three thousand revolutions a minute or upward and in machines provided with means for reciprocating the roll or rolls as heretofore constructed it has been found to be impractical to re ciprocate the rolls at a speed which even approximates the speed of. rotation on account of the strain put upon the various parts of Patented Oct. 18, 1910.

the machine and on account of the vibrations imparted to the machine frame by the m0- mentum of the heavy parts which are reciprocated.

The object of the present invention is to provide a machine comprising a. boiling roll in which the bufiing'roll is reciprocated at such a specs as compared with the speed of rotation as to produce the results which have heretofore been sought to be attained by reciprocating the roll. 1

Other objects of the invention are to improve the construction of butting; machines comprising a butting roll or rolls and render them more eiticicnt in operation.

'ilf'ith these objects in View, my invention contemplates mounting the buifing roll of a bailing machine upon its shaft so as to rotate therewith and be. ca able' of movin vided with a single butting roll or in a machine provided with two or more butting rolls.

My invention also contemplates providing a bufling machine comprising two bufiing rolls with means for reciprocating the rolls simultaneously in o posite directions, whereby the tendency o the momentum of one roll to throw the machine frame into vibration is counteracted by the momentum of the other roll and the rolls can bereeiprocated at a-much higher speed than is practical when both rolls are reciprocated simultaneously in the same direction, as has heretofore been the practice. Broadly considered this feature of my invention is not limited to a construction in which the rolls are mounted to reciprocate ltugitudinally on their shafts, although in tainty of opcration'whieh will be apparent to those skilled in the art.

A butting mac-nine embodying" my invention in its 1.-i'efe1'red form is illustrated in the accmnpanying drawings, but it is to be understood that except as specifically defined in the claims my invention is not. linr itcd to the constructionillustrated but may be otherwise embodied without departing from the spirit thereof. 4

Referring to the drawings, Figure 1 is a view in front elevation of a butting machine embodying the preferred form of my invention; Fig. .2 is a view in front elevation of a portion of the machine illustrated in Fig. 1 illustrating on an enlarged scale the mechanism for reciprocating the balling rolls and Fig". 3 is a detail sectional plan view on the line 3-3 of Fig. 3 illustrating the connections between the ,bell cranks by which the rolls are rcciprocated and their actuating slide.

The frame of the machine illustrated in the drawings consists of a base 1, a central standard 52 upon which is supported a table 3, side plates or standards 1. a cross bar 5 connecting the upper ends of the side plates 4, and a central standard 6 secured to the table In the lower portion of the frame of the machine is mounted the driving; shaft 7 provided with the fast and loose pulleys Sand 9 and having securcdthereto belt pulleys 10 and .11.

12 indicates the usual blower casing in:

which is mounted an exhaust fan which is driven from the pulley 11 by means of a belt 13 in the usual manner.

The machine illustrated in the drawings is provided with two balling rolls as is usual in this class of machines. These boiling rolls are indicated at 14- and 15 and are both mounted upon a shaft 16- journaled in the upper ends of the side plates 4 and in the upper end of the standard 6. A belt pulley 17 is secured to one end of the shaft 16 and the belt 18 over this pullev and over .the pulley 10 on the driving shaft 7 so that the shaft 16 is rotated from the driving shaft.

The construction so far described 15 or may be the same as that of buffing machinesv which have heretofore been devised. In.

such machines, however, provided with means for reciprocating .the butting rolls, the butting rolls have been secured to their shaft so as to rotate and move longitudinally therewith. ,h'ut'h C(Jllrll'llCllOll has necessitated that the butting rolls be reciprocated at a low rate of speed as compared with the speed of rotation of the rolls, as

has heretofore been explained. Inthe machine shown in the drawings tbe'rolls H and 15 are splincd upon the shaft 16 so as to be rotated with the shaft and be capable of a longitudinal reciprocating movement independent of the shaft, and means are prorided for reciprocating the rolls on the shaft sinmltaiu -ously in opposite directions.

ll) mounting the butling rolls to more longitudinally of the shalt. the shaft is not reciprorated as in prior mmstructions and the rolls can be.reeiproraled at a greatly increased speed without liability of injury to the operating mechanism or of throwing the machine frame into vibration. ll) rceiprocating the rolls' simultaneously in opl hsite (lirections'the u-mlenev of the rolls to throw the machine frame into vibration instead of being cumulative i counteractinand the two rolls can he rcciprocated at the. same speed or at a greater speed than would be the case if a single roll were employed.

The butting rolls may be of any wellknown or suitable construction; The means for rcciprocatin the rolls which. I have shown in the drawings compiisc two oppositely disposed bell-'cranks 1S) and 20 pivotally mounted upon projections from the standard 6, the horizontal arms of the bell cranks-.cxtending toward each other and the vertical arms being forked and pivotally connected to rings 21 mounted loosely upon the inner ends of the bolting rolls between collars and 23 secured to the rolls. The openings in the rings 21 are so shaped as to allow a ight vertical movement of the rings as the bell cranks 19 and 20 are 'o cillated The inner ends of the horizontal arms of the bell cranks 19 and J0 are provided with slots in which rectangular blocks l pivot pin 25 passes through these blocks and is secured in the upper forked end of a slide 26 mounted to reciproca e in a vertical guidcway in the standard 6. The

forked upper end of the slide 26 einbraces.

the inner ends of the horizontal arms of the bell cranks as is clearly shown in Fig. 3, and the blocks 2-1 are held. separated by a washer 27. The lower end of the slide '26 is pivotally connected to a rod provided with a strap surrounding an eccentric 29 secured to a. short shaft, .30 journaled in the lower portion of the standard (3. A belt pulley 51 is secured to one end of the shaft e: mounted one of which is shown at. 24in 30 and a belt. 32 passes over this pulley and over the pulley 33 secured to the driving shaft 7 so that the shaft 30 is rotated from the driving shaft.

The relative proportions of the pulleys 17 and and of the pulleys'til and 33 are such that the butting rolls are moved endwise an appreciahle distance during a single revolution of the rolls. These rulle vs may he proportioned to givethe to ls any desiredspeed of reciprocation, the propor tions shown in the drawings being such as to give the rolls about two thousand complete rcciprocations during three thousandrevolutions. v

Having thus HNllCitiQtlillO nature and scope of in invention and having specificallv described a machine embodying the 'prefcrred form thereof. I claim as new and desire to secure by Letters Patent of the a limited States.
